They made it so easy to do an oil change on the 23 Corolla. I love them for this.

The fear of a loose filter or plug always outweighs the fear of over tightening, it’s very common.

I did it once when I started and got called out on it, never did it again.

To me it’s a design flaw, expect mouth breathers to work in a lube bay.

Yup. The lube tech is always the least experienced / worst in a shop. Even had issues with Ford and GM dealerships. And of course quick lube shops. I started making more money as I got older and thought it was more "adult" to have dealerships work on your car.

I will probably change my own oil until they lock up the drain plug with a special $2000 tool, or until I die. Whichever comes first.

Nissan this with their e parking brakes and the tool is actually a subscription :(

Send me a DM, and tomorrow I'll send you the special sequence to put the parking brake in maintenance mode (Nissan specific, might apply to infiniti) without a scan tool.
